LEWIS LIVINGSTON JACKSON, OF ROCKWALL, TEXAS.

COMBINED DISK HARIIROW ANDvLAND-ROLLER.

ne. esagero.

To all whom 'it may concern:

Be it known that I, Lewis L. JACKSON, a citizenof the United States,residing at Rock-4 wall, in the county of Rockwall and State of Texas,have invented certain new and useful Im rovements in a Combined DisklHarrow an Land-Roller, of which the following is aspeciication.

This invention is a combined disk harrow and land roller and has for itsobject to provide an improved device which may be used for thev purposeof a harrow or a roller.

A further object of the invention is to provide improved means forvarying the angle of the rollers or disks with respect to the line or"draft, whereby the depth and the nature of the cut are varied.

A further object of the invention is to provide an implement havingimproved details of construction as will more fully appear hereinafter.

The device is illustrated in the accompanying drawings, in which, .4

Figure 1 is a top plan view of the barrow. Fig. 2 is a vertical sectionon the line 2--2 of Fig. l. Fie'. 3 is an enlarged detail in sideelevation s owing a' swive ing bearing box for the axle of the roller'.

Referrin specifically to theA drawings, 6 indicates t e tongue of theimplement, to which the draft animals are' hitched, and this tonguecarries at itsrear end a seat for the, operator. The roller lframeconsists .of a crossl bar '8 having rearwardly extending arms V9 at theends, and this bar is iixed at the middle to ,the end o thetongue bymeans of a stra .xiclip i which is conveniently i fastened y the samebolts as the seat.

. conne(- ted by 'The im lement includesor contams ltwo rollers. achconsists of a Water tight metal cylinder l1 having 'ournals 12 at theends.` These c linders are ollow and maybe more or less illed with waterthrough holes in the ends closed by plugs 13.

The journal at one end of each cylinder linds bearings in a box 14 ,atthe end of the arm 9. This box is arranged to swivel, being a verticalbolt 15 to ya U-shaped bracket or coupling' 16 which' is fixed to theroar end of the arm 9 by a bolt 17 on which the bracket or couplingcan-swivel in a vertical dans, according to variations in the v erticalplane of the journal incident', to passing over rough or uneven ground.The aring is-iicld between the branches of the bracket Specification ofLetters Patent.

and is free to turn to the desired extent in -ahorizontal plane. Thejournal at the other bearing box 14 similarly fastened to the end of abar 18 which is connected to the lower end of a lever 19 which isful-crumed on a bolt 20 and extends through 'a' slot 21 'in the' tongue,in position infront of the seat; The lever is provided with the usuallatch andy segment 22 to hold the same at adjustment. The respectivebars 18 are connected to, opL posite sides of. the lever 'at the lowerend thereof and extend thence rearwardly to" connection with thejournals .of the respec-A tive rollers. Q Each roller or cylinder is`rovidec'l with. a plurality of or blades 23 extending circumferentiallyaround the cylinder, and located a proper'` distance apart, say sixinches.

In the use of the device as'a harrow, the cutting disks are applied tothe cylinders. By means of the lever 19 the angle ot the axes of thecylinders may be vadjusted as del sired, to give a cut parallel to thelineof vdraft or at a greater or less angle thereto.

"For use as a land roller the disks are removed.

The weight' of the cylinders may also be varied as desired, by placingvmore or less water therein, and when the device zis useful as a rollerfor roads, streets and the like.` i

I claim:

1. The combination of a frame having boxes at opposite sides thereof,rods movab e lengthwise of the frame at the middie thereof and eachhaving a bearing boxI at its re'ar end said bearing boxes being pivotedto swivel'in vertical and horizontal planes,

and rollers located side by side in the frame and having journals in theboxes. .r

2. The combination of a frame having rearwardly extending arms atopposite sides, a lever iulcrumed at the front o the frame; a

pair of rearwardly extending rods yconnected to the lever, bracketsconnected by horizon- 100 tal pivot bolts to "the ends of the arms andthe rods, bearing boxes mounted on vertical ivots in the brackets, and apair of rollers raving journals in said boxes.

In testimony whereof I aHix my signature, A105 in presence of twoWitnesses.
